The article provides an example of a project in physics concerning clocks in which gifted pupils engage in high-level problem solving while developing technical knowledge and appropriate scientific methodology. Drawings illustrate the principles taught by the project. (Author/DB)

Describes school science activities in which students race model cars built from mousetraps, construct inventions using discarded junk, and compete in an egg dropping contest. (SL)

Experiments with exercises that are distinguished from those employed with elite students by reducing competition and increasing cooperation through the use of tests against nature, large dynamic ranges in performance, initial prototype designs, and alternative methods of recording and presenting results. Finds that formulating easily understood…

Describes an extended problem-solving activity utilizing drift-bottles that encourages students to deduce probable and great-circle drift-bottle routes, to use logic based on unit calculations, and to estimate the distance traveled and the minimum velocity of these drift-bottles. Includes materials needed, learning objectives, procedures,…

Educationally successful electronic network activities involving microcomputers and long-distance networks include a student newswire, joint social science projects, and joint science projects. A newswire activity, such as "The Computer Chronicles," can provide a wide range of audiences for writing, a functional environment for reading, and a…

Science fairs represent the culmination of student research efforts under the guidance of teachers and other persons interested in science topics. The total scientific process should be involved in the development of a project which results in a science fair exhibition. The student should learn to recognize problems, plan an experiment, gather and…

Contends that school science programs should return to the visionary programs of the 1960's, which developed logical thinking and problem solving. These have since given way to a barren emphasis on fact acquisition and "cookbook" lab activities. (TE)

Argues that science programs developed during the 1960's should be replaced by "science/technology/society" (S/T/S) programs, which build on students' curiosity and concern about local problems. (TE)

Research on the development of ability to control variables during adolescence is reviewed. The first section discusses studies by Piaget and his collaborators, replications of Piaget's studies, and related studies by other investigators. Factors which influence performance on controlling variables tasks are delineated; the existence of Piaget's…
